  • Fibrothorax is the end stage of chronic pathologic processes of pleura such as hemothorax, empyema, or tuberculous effusion. The pleural space become adherent and obliterated, and the lung parenchyma is covered by a thick, fibrous, unexpandable "peel", so the lung function is diminished markedly with impaired ventilation and oxygenation. Constrictive pericarditis is often accompanied fibrothorax, also cardiac and hemodynamic function is deteriorated. Surgical relief of these fibrous peels causes remarkable improvement in pulmonary function, cardiac and hemodynamic function, and subjective symptoms. We experienced a case of bilateral fibrothorax combined with constrictive pericarditis which occured 3 years after bilateral tuberculous effusion. Decortication and percardiectomy were done at the same time through bilateral submammary thoracotomy with sternal transection. Comparing postoperative Peripheral venous pressure, Circulation time, Pulmonary function test, Arterial blood gas analysis, Subjective symptoms with preoperative conditions showed noticeable improvement.provement.

  • Objectives: The purpose of this study was to examine the relationship between limited oral function and cardiovascular disease in adults over 40 years of age. Methods: Data from the Seventh Korean National Health and Nutrition Examination Survey (2016-2018) was used. In this study, 8,766 adults over the age of 40 years were included as study subjects. They completed a health survey which included current prevalence of hypertension, stroke, myocardial infarction, and angina pectoris, as well as information about blood tests, physical measurements, and oral examinations. Statistical analyses were carried out using complex sample cross-tabulation analysis, general linear model, and logistic regression analysis. Results: The study showed that limited oral function was experienced by patients with stroke (61.3%), myocardial infarction (49.1%), cardiovascular disease (38.5%), hypertension (38.1%), and angina (36.4%) (p<0.05). In patients with stroke, the risk of limited oral function was 2.393 times higher than in patients without stroke. Patients with hypertension were 1.233 times more at risk of speaking difficulty than those without hypertension. Conclusions: Limited oral function is associated with cardiovascular disease. To improve oral health, it is necessary to provide integrated, health-based oral care.

  • Objective: The purpose of this study was to changes in respiratory function due to differences in mask blocking grade, and effects on cardiovascular function during aerobic exercise. Design: Comparative study using paired t-test and analysis of variance measures. Methods: Male and female subjects were randomly divided into 4 groups according to mask blocking grade and measured respiratory functions before and after wearing the mask using spirometers, and their cardiovascular capabilities were measured using pulse oxygen meters and blood pressure meters before and after running for 10 minutes wearing mask. Used paired t-test, one-way ANOVA and Bonferroni post-test to compare the differences according to the mask blocking grade. Results: The experimental results verified that three groups except for the Non-mask group had a significant reduction in all values of FVC, FEV1, MVV, and PEF after wearing a mask compared to those before wearing a mask(p<0.05). Also a significant difference in cardiovascular functions was also observed after aerobic exercises wearing mask in all groups and there was a significant difference between all four groups(p<0.05). Conclusions: Lung patients with poor breathing, elderly and children with poor lung function, and professional groups who need to wear masks and take high-intensity work or aerobic movements are encouraged to take frequent breaks in advance, wear masks and social distancing at moderate and low levels.

  • BACKGROUND: The function of left atrium (LA) is difficult to assess because of its ventricle-dependent, dynamic movement. The aim of this study was to assess LA function using velocity vector imaging (VVI) and compare LA function in patients with hypertrophic cardiomyopathy (HCMP) and left ventricular hypertrophy (LVH) with normal controls. METHODS: Fourteen patients with HCMP (72% male, mean age of 52.6 ± 9.8), 15 hypertensive patients with LVH (88% male, mean age of 54.0 ± 15.3), and 10 age-matched controls (83% male, mean age of 50.0 ± 4.6) were prospectively studied. Echocardiographic images of the LA were analyzed with VVI, and strain rate (SR) was compared among the 3 groups. RESULTS: The e' velocity (7.7 ± 1.1; 5.1 ± 0.8; 4.5 ± 1.3 cm/sec, p = 0.013), E/e' (6.8 ± 1.6; 12.4 ± 3.3; 14.7 ± 4.2, p = 0.035), and late diastolic SR at mid LA (-1.65 ± 0.51; -0.97 ± 0.55; -0.82 ± 0.32, p = 0.002) were significantly different among the groups (normal; LVH; HCMP, respectively). The e' velocity, E/e', and late diastolic SR at mid LA were significantly different between normal and LVH (p = 0.001; 0.022; 0.018), whereas LA size was similar between normal and LVH (p = 0.592). The mean late diastolic peak SR of mid LA was significantly correlated with indices of diastolic function (E/e', e', and LA size). CONCLUSIONS: The SR is a useful tool for detailed evaluation of LA function, especially early dysfunction of LA in groups with normal LA size.

  • Ginseng is one of the most widely used herbal medicines and is reported to have a wide range of therapeutic and pharmacological applications. Ginseng may also be potentially valuable in treating cardiovascular diseases. Research concerning cardiovascular disease is focusing on purified individual ginsenoside constituents of ginseng to reveal specific mechanisms instead of using whole ginseng extracts. The most commonly studied ginsenosides are $Rb_1$, $Rg_1$, $Rg_3$, $Rh_1$, Re, and Rd. The molecular mechanisms and medical applications of ginsenosides in the treatment of cardiovascular disease have attracted much attention and been the subject of numerous publications. Here, we review the current literature on the myriad pharmacological functions and the potential benefits of ginseng in this area. In vitro investigations using cell cultures and in vivo animal models have indicated ginseng's potential cardiovascular benefits through diverse mechanisms that include antioxidation, modifying vasomotor function, reducing platelet adhesion, influencing ion channels, altering autonomic neurotransmitters release, and improving lipid profiles. Some 40 ginsenosides have been identified. Each may have different effects in pharmacology and mechanisms due to their different chemical structures. This review also summarizes results of relevant clinical trials regarding the cardiovascular effects of ginseng, particularly in the management of hypertension and improving cardiovascular function.

  • Cerebral air embolism combined with cardiomyopathy secondary to pulmonary barotrauma is rare. Here, we report an unusual case of cerebral air embolism combined with transient cardiomyopathy secondary to large bulla rupture during a pulmonary function test after lung cancer surgery. The patient experienced loss of consciousness. Computed tomography and magnetic resonance imaging suggested a cerebral air embolism. Electrocardiography showed ST-segment elevation and abnormally high plasma levels of cardiac enzymes. Echocardiography and coronary angiography suggested cardiomyopathy. The patient was discharged with no sequelae.

  • Background: Left ventricular (LV) hypertrophy caused by aortic valve stenosis (AS) leads to cardiovascular morbidity and mortality. We sought to determine whether aortic valve replacement (AVR) decreases LV mass and improves LV function. Materials and Methods: Retrospective review for 358 consecutive patients, who underwent aortic valve replacement for degenerative AS between January 1995 and December 2008, was performed. There were 230 men and 128 women, and their age at operation was $63.2{\pm}10$ years (30~85 years). Results: There was no in-hospital mortality, and mean follow-up duration after discharge was 48.9 months (2~167 months). Immediate postoperative echocardiography revealed that LV mass index and mean gradient across the aortic valve decreased significantly (p<0.001), and LV mass continued to decrease during the follow-up period (p<0.001). LV ejection fraction (EF) temporarily decreased postoperatively (p<0.001), but LV function recovered immediately and continued to improve with a significant difference between preoperative and postoperative EF (p<0.001). There were 15 late deaths during the follow-up period, and overall survival at 5 and 10 years were 94% and 90%, respectively. On multivariable analysis, age at operation (p=0.008), concomitant coronary bypass surgery (p<0.003), lower preoperative LVEF (<40%) (p=0.0018), and higher EUROScore (>7) (p=0.045) were risk factors for late death. Conclusion: After AVR for degenerative AS, reduction of left ventricular mass and improvement of left ventricular function continue late after operation.

  • A preoperative prediction of postoperative pulmonary function after the pulmonary resection should be made to prevent serious complications and postoperative mortality. There are several methods to predict postoperative lung function but the 99m7c-MAA perfusion lung scan is known as simple, inexpensive and easily tolerated method for patients. We studied the accuracy of the perfusion lung scan in predicting postoperative lung function on 34 patients who received either the resection of one lobe(17 patients) or 2 lobes(2 patients) or pneumonictomy(15 patients). We performed pulmonary function test and lung scan immediately before the operation and calculated the postoperative lung function by substracting the regional lung function which will be rejected. We compared this predictive value to the observed pulmonary function which was done 20 days after the surgery. We also compared the data achieved from 12 patients ho received open thoracotomy due to intrathoracic disease that are not confined in the lung. The correlation coefficient between the predicted value and observed value of FEVI .0 was 0.423, FVC was 0.557 in the pneumonectomy group and FEVI . 0 was 0.693, FVC was 0.591 in the lobectomy group. The correlation coefnclent between the'postoperative value and preoperative value of FEVI .0 was 0.528, FVC was 0.502 in the resectional group and FEVI .0 was 0.871, FVC was 0.896 in the comparatives. We concluded that the perfusion lung scan is accllrate in predicting post-resectional pulmonary function.
